Details

A leaking cistern-to-pan connection is one of the most common issues in bathroom plumbing. Often, standard washers supplied with new toilets are too thin to compensate for any slight unevenness between the pan and the cistern. This results in persistent, slow leaks that can damage your bathroom floor and cabinet over time.

This extra-thick 17mm washer is the solution. The additional thickness ensures that when you tighten the coupling bolts, the foam compresses fully to create a watertight seal, even if the surfaces aren’t perfectly aligned. It’s a simple, inexpensive upgrade that provides peace of mind and saves you from the frustration of re-tightening or re-sealing your toilet cistern.
